I believe thats what the single screw class proposed at the meeting at Mobile Marine Models place was supposed to encourage Davey.
It gets complicated when a single screw with rudder is up against a single with Kort Nozzle, or twin independant control, if we were to say 'single screw/with rudders' only the rest would spit the dummy and we can mix & match all the aforementioned types of control and have same outcome.
Having said that...its all down to skill at the sticks in my opinion and a good skipper is going to shine, whatever he uses in whatever class, John Hughes, who you went round the course with, has lovely 'classic' tug...the 'stormcock' and he loves using it despite being a whizz with his other more modern tug.
The lads down south were very keen on attending a 'Scottish Nationals' should we have one, and I would certainly hope to support 'classics' in that. It would mean that it would be like this years nationals...held over two days for the sake of getting it all in, but well worth it in my opinion...what do you thinK?
